I had a stent placed one week ago today, was back in the hospital day before yesterday having an EGD and colonoscopy to tract down the source of some rectal bleeding (so they wouldn't have to take me off Plavix - results are internal hemorrhoids), yesterday I felt okay, today I'm exhausted and shaky. Shouldn't opening a blocked artery make me feel better? How long should it take to recover from 2 episodes of conscious sedation within the week? Or is there something else going on?
